Definitions

  • This invention is related to the field of automotive lighting devices, and more particularly, to the way light patterns are managed when using a Dynamic Bending Light (DBL) functionality.
  • DBL Dynamic Bending Light
  • Dynamic Bending Lights are increasingly present in current automotive lighting devices, becoming an upgrade to standard headlights and designed to make driving at night easier and safer.
  • Mechanic-based solutions turn the lighting source as the steering wheel does, by means of an angular movement converter which directly uses the turning of the steering wheel to induce a turning in the lighting source.
  • the lights will turn in whatever direction the wheel does, and this range of motion allows the lights to illuminate the road even when taking sharp turns or turning quickly.
  • the invention provides an alternative solution for providing a dynamic bending light by a method for controlling a light pattern according to claim 1 and an automotive lighting device according to claim 8.
  • Preferred embodiments of the invention are defined in dependent claims.
  • the invention provides a method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle, wherein a dynamic portion of the light pattern is provided by a matrix arrangement of light sources, the method comprising the steps of
  • This method provides a controlled light pattern which includes a Dynamic Bending Light functionality, provided by the same lighting device that provides, for example, the low beam functionality, without moving parts and also being able to adapt to other driving circumstances, such as the driving speed or the presence of cars in the opposite direction.
  • a Dynamic Bending Light functionality provided by the same lighting device that provides, for example, the low beam functionality, without moving parts and also being able to adapt to other driving circumstances, such as the driving speed or the presence of cars in the opposite direction.
  • the shifting in the operation should be understood as displacing one or more columns to the right or to the left, depending on the movement of the steering system, the light pattern provided in the matrix: if the original pattern in one row is, e.g., 0-0-1-1-0, where 0 is a light turned off and 1 is a light turned on, after a 1 column shift to the left, the resulting pattern would be 0-1-1-0-0, and after a 1 column shift to the right, the resulting pattern would be 0-0-0-1-1.
  • the subsequent creation of a third portion should be understood as the activation of the light sources which are associated to the blank spaces created when shifting the first portion.
  • the second portion would remain the same 0-0-1, but the second portion would shift 2 columns to the right, creating 2 columns of blank space: 0-0-1-1-0-0-0.
  • the creation of a third portion between the first portion and the second portion would "fill this blank space", so that the final light pattern, after joining the first portion, the second portion and the third portion would be 0-0-1-1-1-1-1-0-0-0.
  • the first "1" would belong to the second portion, the next two “1”s would belong to the third portion and the remaining two “1”s would belong to the first portion, which has been shifted to the right.
  • the light pattern further comprises a fixed beam provided by a first group of solid-state light sources
  • the matrix arrangement comprises a second group of solid-state light sources, wherein the sum of the fixed beam and the dynamic portion gives result in the light pattern.
  • solid state refers to light emitted by solid-state electroluminescence, which uses semiconductors to convert electricity into light. Compared to incandescent lighting, solid state lighting creates visible light with reduced heat generation and less energy dissipation.
  • the typically small mass of a solid-state electronic lighting device provides for greater resistance to shock and vibration compared to brittle glass tubes/bulbs and long, thin filament wires. They also eliminate filament evaporation, potentially increasing the life span of the illumination device.
  • Some examples of these types of lighting comprise semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer light-emitting diodes (PLED) as sources of illumination rather than electrical filaments, plasma or gas.
  • the combination of a fixed beam and a matrix beam arrangement is a very common solution for current headlamps.
  • the matrix arrangement is in charge of providing some lighting functionalities and, with the method of the invention, this matrix beam is also configured to provide a Dynamic Bending Light functionality without adding any additional element.
  • the third portion is an interpolation between the first portion and the second portion
  • the third portion fills the gap created when the first portion is shifted according to the turning of the vehicle.
  • the way of defining the luminous intensity of each pixel would be an interpolation between the column of the shifted first portion which is closest to the third portion and the column of the second portion which is closest to the third portion. In some particular embodiments, this interpolation is linear.
  • the light pattern is a low beam pattern and the first portion comprises the cut-off of the low beam pattern.
  • the cut-off is a diagonal line of the low beam pattern, and its shape is important in automotive regulations.
  • the fact that this cut-off belongs to the first portion means that this cut-off is being shifted when the vehicle turns. This is advantageous since the shifted pattern must also comply with the regulations.
  • the invention may be also applied to other lighting functionalities without a cut-off, such as the high beam.
  • the angular displacement of the steering system is sensed and converted into a number of positions to shift, and then the step of shifting is carried out using this number of positions to shift.
  • the matrix of solid-state light sources may have many different angular resolutions. Depending on the number and arrangement of these light sources, resolution may vary from 0.01° per light source up to 0.5° per light source. Hence, the angular position of the steering wheel may be translated in a different number of columns of the light array, depending on the density of these light sources in the array arrangement.
  • this method further comprises the step of internally checking the luminous intensity in one point of the light pattern.
  • the invention provides an automotive lighting device comprising
  • This automotive lighting device is configured to provide a Dynamic Bending Light functionality without moving parts, and using elements which are already available, but with a new configuration.
  • the matrix arrangement comprises at least 2000 solid-state light sources.
  • This invention can be useful for many types of lighting matrix/array-based technology, from the simplest one, with only a few thousands light sources, to more advanced ones, with several hundred thousand light sources.
  • Figure 1 shows a general perspective view of an automotive vehicle 100 comprising an automotive lighting device 10 according to the invention.
  • This automotive vehicle 100 comprises a steering system 11 and a lighting device 10.
  • the lighting device 10 comprises a plurality of groups of LEDs 2 and a control centre 7 which is configured to control the operation of these groups of LEDs.
  • the control centre 7 is configured to modify the configuration of the LEDs 2 when the steering wheel of the vehicle is activated.
  • Figure 2 shows a closer view of a particular embodiment of a lighting device 10 according to the invention.
  • This lighting device 10 comprises a first group of LEDs 2 which are grouped in a first lighting module 4 and a second group of LEDs 2 which are arranged in a matrix configuration 6.
  • This matrix configuration 6 is a high-resolution module, having a resolution greater than 1000 pixels. However, no restriction is attached to the technology used for producing the projection modules.
  • a first example of this matrix configuration comprises a monolithic source.
  • This monolithic source comprises a matrix of monolithic electroluminescent elements arranged in several columns by several rows.
  • the electroluminescent elements can be grown from a common substrate and are electrically connected to be selectively activatable either individually or by a subset of electroluminescent elements.
  • the substrate may be predominantly made of a semiconductor material.
  • the substrate may comprise one or more other materials, for example non-semiconductors (metals and insulators).
  • each electroluminescent element/group can form a light pixel and can therefore emit light when its/their material is supplied with electricity.
  • the configuration of such a monolithic matrix allows the arrangement of selectively activatable pixels very close to each other, compared to conventional light-emitting diodes intended to be soldered to printed circuit boards.
  • the monolithic matrix may comprise electroluminescent elements whose main dimension of height, measured perpendicularly to the common substrate, is substantially equal to one micrometre.
  • the monolithic matrix is coupled to the control centre so as to control the generation and/or the projection of a pixilated light beam by the matrix arrangement 6.
  • the control centre is thus able to individually control the light emission of each pixel of the matrix arrangement.
  • the matrix arrangement 6 may comprise a main light source coupled to a matrix of mirrors.
  • the pixelated light source is formed by the assembly of at least one main light source formed of at least one light emitting diode emitting light and an array of optoelectronic elements, for example a matrix of micro-mirrors, also known by the acronym DMD, for "Digital Micro-mirror Device", which directs the light rays from the main light source by reflection to a projection optical element.
  • DMD Digital Micro-mirror Device
  • an auxiliary optical element can collect the rays of at least one light source to focus and direct them to the surface of the micro-mirror array.
  • Each micro-mirror can pivot between two fixed positions, a first position in which the light rays are reflected towards the projection optical element, and a second position in which the light rays are reflected in a different direction from the projection optical element.
  • the two fixed positions are oriented in the same manner for all the micro-mirrors and form, with respect to a reference plane supporting the matrix of micro-mirrors, a characteristic angle of the matrix of micro-mirrors defined in its specifications. Such an angle is generally less than 20° and may be usually about 12°.
  • each micro-mirror reflecting a part of the light beams which are incident on the matrix of micro-mirrors forms an elementary emitter of the pixelated light source.
  • the actuation and control of the change of position of the mirrors for selectively activating this elementary emitter to emit or not an elementary light beam is controlled by the control centre.
  • the matrix arrangement may comprise a scanning laser system wherein a laser light source emits a laser beam towards a scanning element which is configured to explore the surface of a wavelength converter with the laser beam. An image of this surface is captured by the projection optical element.
  • the exploration of the scanning element may be performed at a speed sufficiently high so that the human eye does not perceive any displacement in the projected image.
  • the scanning means may be a mobile micro-mirror for scanning the surface of the wavelength converter element by reflection of the laser beam.
  • the micro-mirrors mentioned as scanning means are for example MEMS type, for "Micro-Electro-Mechanical Systems".
  • the invention is not limited to such a scanning means and can use other kinds of scanning means, such as a series of mirrors arranged on a rotating element, the rotation of the element causing a scanning of the transmission surface by the laser beam.
  • the light source may be complex and include both at least one segment of light elements, such as light emitting diodes, and a surface portion of a monolithic light source.
  • Figure 3 shows a light pattern 1 projected by this lighting device.
  • the first light module projects a fixed beam 3 and the matrix arrangement, in this case, is configured to project the remainder 5 of a low beam pattern.
  • this remainder 5 comprises the cut-off of the light pattern.
  • this remainder 5 comprises the cut-off of the light pattern.
  • Figure 4a shows a division in this remainder 5 of the low beam pattern, projected by the matrix arrangement.
  • This remainder 5 has been divided into a first portion 51 and a second portion 52.
  • the first portion 51 will be shifted with the turning of the steering system of the vehicle, while the second portion 52 will remain still.
  • Figure 4b shows the shifting of the first portion 51 to the right.
  • the first portion comprises the cut-off and is shifted to the right according to the movement of the steering system of the vehicle.
  • a third portion 53 is created between the first portion and the second portion, to fill the gap between them.
  • the structure of this third portion is a linear interpolation between the last column of the first portion and the last column of the second portion, which are the columns which surround the gap which is filled by the third portion.
  • Figures 5a and 5b show a similar example, but to the left.
  • the first portion is on the left, and the cut-off is shifted with the first portion, but the second portion corresponds to a different profile than the second portion in the case of a right turn.
  • the third portion in any case, is a linear interpolation between the first and the second portions.
  • Figure 6a shows a detailed view of the operation of this matrix arrangement.
  • 20 columns and 10 rows of the matrix arrangement are seen.
  • one number from 1 to 10 represents the luminous intensity of the associated LED, in intervals of 10%.
  • a number "4" represents 40% of luminous intensity
  • a number 5 represents 50% of luminous intensity.
  • a method according to the invention converts this angular displacement into a number of rows, according to the resolution of the matrix arrangement. For example, in cases where the resolution is 0.2o per LED column, an angular displacement of 1o would be converted into 5 LED columns.
  • control centre After calculating the number of LED columns, the control centre divides the dynamic portion in a first portion and a second portion and shifts the operation of the light sources of the matrix arrangement which are associated to the first portion 5 columns to the right, resulting an operation as the one shown in figure 6b .
  • a blank space is shown between the shifted first portion 51 and the second portion 52, which remains still.

  • the operation of the LEDs of the same 20 columns have changed, thus providing a Dynamic Bending Light functionality 1o to the right side of the automotive vehicle. Since a matrix arrangement may include several hundred thousand of LEDs and the resolution is usually comprised between 0.01o per LED column and 0.5o per LED column, this shifting usually involves many columns of LEDs.
  • the lighting points which are defined in official regulations are providing a suitable value of luminous intensity.
  • the luminous intensity in point 50L may be checked to verify it this accomplishes luminous standards.
  • the control centre may apply in these cases a correction of the value of the luminous intensity, depending on the luminous intensity of the fixed beam.
